BACKGROUND

Computers and computer software make up a very important part of modem life and business. In today's business environment, for any organization to stay competitive, it is imperative that it uses computers and software applications to manage data, customers, employees, finances, etc. Generally speaking, organizations use specialized application to use one or more of their various operations.

For example, businesses use accounting software to manage their accounting, tax, payroll, and other accounting related functions, whereas customer relationship management (CRM) software is used to manage customer accounts, orders, etc. Most businesses implement their core enterprise applications such as enterprise resource planning (ERP) and CRM at different times, using products developed by different vendors. This results in the problem of how to integrate disparate systems in most cost effective, efficient and effective manner.

For example, a business may be using an ERP system to manage inventory and a separate CRM system to manage customer data. In such a scenario, when a new customer account is created in the CRM system, its attached item order may not be automatically and immediately reflected in the ERP system. Similarly, when delivery of an item is received in the inventory system, it may not be automatically applied to backlog of orders received in the CRM system. Such lack of communication and data sharing between various applications may result in considerable loss of efficiency and competitiveness for businesses.

One solution to the problem of integrating such disparate applications is to custom develop solutions that facilitate communication and sharing of data between such disparate applications. For example, an integration developer may develop custom application that interacts with both of the CRM and the ERP to keep them apprised of any changes in the data that need to be shared among them. However, developing and constantly updating such custom integration application is time consuming and costly.

Several business integration products, such as Microsoft™ BizTalk™, Tivoli™, etc., provide framework to integrate a number of business applications. However, such integrations products are technically complex and because they require special expertise on the part of the end user business, they increase the total cost of ownership (TCO) on the part of small to medium business entities using such products. Therefore, there is a need to provide an application integration framework that allows for integrating several business applications in highly automated and yet cost effective manner.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

An application integration system used to integrate a plurality of applications includes a plurality of integration adapters, each communicating with an application and an integration engine including a messaging broker, an integration database and a schema mapping database. The application integration system also uses a plurality of tools and components interactively working with the messaging broker. The application integration system allows integrating various applications and at the same time provides ease of change to users of such applications by providing a framework that may be used to customize and configure integrations leading to significant reduction in total cost of ownership to the businesses.

An alternate embodiment of the application integration system performs the various functions such as identifying compound document, breaking down compound document into simple messages, determining if any pre-action needs to be applied to the simplified messages, applying schema mapping to the simplified messages, applying various default values to the simplified messages and applying any post-action procedures to the messages outside of the messaging broker. In such an implementation an adapter proxy within the integration engine may be used to communicate the outgoing message from the integration engine to any destination application.

In an alternate embodiment of the application integration system, the integration engine may also include a data synchronization module which may allow a user to synchronize data between a plurality of applications. The data synchronization tool may allow a user to synchronize two applications when first implemented using the integration system by allowing user to bring the current status of various data between such two applications in synchrony with each other.

An alternate embodiment of the application integration system includes an integration monitor that allows a user to monitor the status of data transfer between a plurality of applications. Using the integration monitor, a user may monitor the status of any set of data being transferred at various stages of such transfer. For example, the integration monitor allows the user to monitor when a record is being transferred from a first application to a second application, whether proper set of pre-action and post-action procedures were applied to the record or not.

Yet another embodiment of the application integration system provides a settings administration module which allows a user to set various default settings for the use of the application integration system. Using the settings administration module, a user may set various default values to be applied by the default value application module, various post-action to be applied to the data being transferred through the integration engine, etc. Additionally, using the administration module, a user may add new entities for integration, update mapping logic of existing entities and deploy the updated mapping logic.

Application Integration System

FIG. 3 illustrates a block diagram of an example implementation of an application integration system 200. The application integration system 200 is shown to be used in integrating a customer relationship management (CRM) system 202 to an enterprise resource planning (ERP) system 204. However, any other application such as an accounting application, a human resource management system, etc., may be integrated using the application integration system 200. Moreover, while the current implementation is shown to integrate only two applications, an alternate implementation may be used to integrate a larger number of applications with each other. Moreover, as one of ordinary skill in the art would recognize, any of the various blocks of the application integration system 200 may be implemented using software, hardware, firmware or any combination thereof. Similarly, the various sections of the application integration system 200 may be implemented on various nodes of the network 10. For example, the CRM application 202 may be running on a server node of the network 10, while the ERP application 204 may be running on a computer node of the network 10.

Now referring to FIG. 3, the application integration system 200 may include an integration engine 206, a CRM inbound adapter 208, a CRM outbound adapter 210, an ERP inbound adapter 212, an ERP outbound adapter 214, and a message transport module 216. The CRM application 202 and the ERP application 204 may send messages to the integration engine 206 via their respective outbound adapters 210 and 214 and the message transport module 216. The integration engine 206 may send messages to the CRM application 202 and the ERP application 204 via their respective inbound adapters 208 and 212. The adapters 208-214 may be internal to the integration engine 206 or they may be provided as separate modules operating with their respective applications.

The integration engine 206 includes a messaging broker 220, a plurality of components interacting with the messaging broker 220, a plurality of tools facilitating a user's interactions with the integration engine 206, a schema mapping module 222 and an integration database 224. The messaging broker 220 includes a receive adapter 226, a message box 228, a send adapter 230 and an orchestration module 232. The receive adapter 226 may pick up messages from the message transport module 216 and store the message in the message box 228. The orchestration module 232 may pick up messages from the message box 228 based on any predetermined criteria to process such messages. Once the message is processed according to the various components of the integration engine 206, it is communicated to its destination application by the send adapter 230.

The orchestration module 232 interacts with a compound document module 234, a pre-action module 236, a map application module 238, a default value application module 240, and a post-action module 242 to process various messages received in the message box. Specifically, after selecting a message to be processed, the orchestration module 232 it activates the compound document module 234, which determines if the message is a compound document or a simple document. A compound document may contain information about various entities that may contain several simple messages. The compound document module 234 may decide the sequence of simple messages contained in such entities to preserve referential integrity of data in the destination application. If the message is determined to be a compound document, the compound document module 234 breaks it down into a number of simple documents for further processing. For example, if the compound document module 234 determines that the message indicates that four new contacts were generated in the message generating application, it breaks it down into four separate messages, each representing a single contact generation message.

Subsequently the orchestration module 232 invokes the pre-action module 236 to determine if any dependent messages need to be processed before the message being currently processed and if so determined, it puts the message being currently processed into a queue before further processing. Once it is determined that a particular message is ready to be processed, the orchestration module 232 invokes the map application module 238. The map application module 238 uses one more mapping schema stored in the schema mapping module 222 to generate an outgoing message in response to the message being currently processed.

The mapping schema may be, for example, a dynamic link library (DLL) assembly file that processes a message from a message generating application to a message that need to be sent to the message destination application. For example, if the incoming message indicates that a new account has been created in the message generating application, such as the CRM application 202, the mapping schema may generate a message to a destination application, such as an ERP application 204 that a new account needs to be generated and passes the parameters from the incoming message to the destination application for generating such an account.

Once a mapping schema has been applied to a message, the orchestration module 232 invokes the default value application module 240. The default value application module 240 may be provided a number of default values from an administrator during the setting up of the integration engine 206. The default value application module 240 applies one or more such default values to the outgoing message. Subsequently, the orchestration module 232 invokes the post-action module 242. The post-action module 242 may use any customer logic that may need to be applied to the outgoing message, where such customer logic may be provided by the administrator during the setting up of the integration engine 206.

The integration engine 206 also includes a setting administration module 250, an integration monitor 252 and a data synchronization module 254. The setting administration module 250 may be used by an administrator to set up any default values, to set up any post-action rules that need to be applied to an outgoing message, etc. The integration monitor 252 may be used by an administrator to monitor the functioning of the integration engine 206. Using the integration monitor 252, the administrator can ensure that each of the modules 234-242 are properly functioning to transform an incoming message to an outgoing message.

The data synchronization module 254 may be used by an administrator to synchronize two applications with each other using the integration engine 206. For example, using the data synchronization module an administrator can perform initial set up of two applications so that various data in both applications are synchronized.

The integration database 224 may store information about the applications being integrated. For example, the integration database 224 may store information about the entities which are integrated, information about what kind of messages should be determined to be compound documents, etc. The integration database 224 may also store message related information that may be used by the integration monitor 252. Furthermore, the integration database 224 may also store settings configured by the setting administration tool 250, pre-action information to be used by the pre-action module 236, additional schema maps used by the integration engine 206, various default values stored in the integration database, etc.

Now referring to FIG. 4, it illustrates an alternate implementation of the application integration system 200 of FIG. 3. A number of blocks in FIG. 4 are similar to the blocks in FIG. 3 and therefore are referred to by the same numerals as used in FIG. 3. One of the major differences between the implementations illustrated in FIGS. 3 and 4 is that while the integration engine 206 as illustrated in FIG. 3 has the messaging broker 220 receiving an incoming message and the messaging broker 220 performing the transformation, the integration engine 206 as illustrated in FIG. 4 has the transformation of the incoming message performed outside the messaging broker 220. Thus as illustrated in FIG. 4, the messaging broker 206 may merely monitor the performance of the various components 234 to 242. Upon completion of the transformation, the adapter proxy module 244 may communicate the outgoing message to the destination application.

The functioning of the application integration system 200 is described below in FIG. 5 by showing an integration of an update to the CRM application 202 into the ERP application 204. However, as one of ordinary skill in the art would recognize, the application integration system 200 may also be equally used to integrate an update into the ERP application 204 into the CRM application 202. Similarly, in an alternate implementation, an update into the CRM application 202 may be integrated simultaneously into the ERP application 204 and one or more other applications working with the application implementation system 200.

FIG. 5 illustrates a flowchart of an application integration program 300 using the various components of the application integration systems described in FIGS. 3 and 4. The application integration program 300 is illustrated to show transformation of a message from the CRM application 202 and communicating of the transformed message to the ERP application 204. However, as one of ordinary skill in the art would recognize, similar program may provide transformation of a message from the ERP application 204 and communication of the message to the CRM application 202 as well.

At a block 302 the CRM application 202 recognizes that a new record has been created by a user and therefore it generates a message to the CRM outbound adapter 210 informing of such record creation. In response to the message from the CRM application 202, at a block 304 the CRM outbound adapter 210 submits a message to the message transport module 216. The receive adapter 226 of the messaging broker 220 may be constantly listening to the message transport 216 and therefore, at a block 306 the receive adapter 226 picks up the message from the message transport 216.

At a block 308 the receive adapter 226 stores the incoming message in the message box 228. Subsequently, at a block 310, the orchestration module 232 picks up the message from the message box in accordance with any predetermined criteria and performs message transformation using the various components 234-242. The process of message transformation is described in further detail below in FIG. 6.

Upon completion of the message transformation, at a block 312, the transformed message is sent to the send adapter 230. The send adapter 230 identifies the destination application for the transformed message and, at a block 314, the send adapter 230 communicates the message to the inbound adapter of the destination application. In the implementations illustrated in here the destination application is the ERP application 204, therefore, at the block 314, the transformed message is sent to the ERP inbound adapter 212. Note that if the integration engine 206 was implemented as illustrated in FIG. 4, at the block 312, the adapter proxy 244 would communicate the transformed message to the inbound adapter of the destination application.

Subsequently, at a block 316, the destination application undertakes any requisite action in response to the transformation message, such as creation of a record, updating of a record, deletion of a record, etc., which would result in the destination application being synchronized to the application originating the message to the integration engine 206.

Now referring to FIG. 6, an exemplary flowchart illustrates functioning of a message transformation program 350 that is undertaken at the block 310. At a block 352, the orchestration module 232 invokes the compound document module 234, which determines if the incoming message is a compound document or a simple document, if the incoming document is a compound document, the compound document module 234 breaks down the compound document into a series of simple documents.

Subsequently, at a block 354, the incoming simple document or the simple document received from the compound document module 234 is processed by the pre-action module 236. The pre-action module determines if before transforming of a message if any pre-action need to be applied to such a message or not. For example, the pre-action module 236 may determine that according to specified pre-action logic, a dependent message need to be generated before processing of the current message.

After being processed by the pre-action module 236, at a block 356 any transformation mapping in applied to the message by the map application module 238. The map application module 238 may select a transformation mapping schema from the schema mapping module 222 based on the message type, the originating application, the destination application, any user specified special logic, etc., and perform the transformation.

After performing the message transformation, at a block 358, the default value application module 240 determines if any default value need to be applied to the transformed message. Such default values may be set up with the original installation of the integration engine 206 or provided by a user using the setting administration module 244.

Subsequently, at a block 360, the post-action module allows a user to link any custom logic to the transformed outgoing message. A user may specify such custom logic by creating his or her own assembly and linking such assembly to the post action module via the setting administration module 244. At this point the transformed message may be deemed ready to be sent to the destination application and is handed over to the send adapter 230.

As one of ordinary skill in the art would appreciate, one or more sections of the application integration system 200 may be implemented using hardware, software, firmware or any combination thereof. Moreover, as one of ordinary skill in the art would appreciate, not all the blocks of the application integration program 400 need to be performed for a given implementation of the application integration system 200. As some of the blocks of the application integration program 400 may be used primarily to increase the efficiency of the application integration program 400, one or more such blocks may be omitted in a given implementation without affecting the functionality of the application integration system 200. Moreover, one or more of the blocks in the application integration program 400 may also be implemented in an alternate order without affecting the functionality of the application integration system 200.

Now referring to FIG. 7, an example of a multiple application integration system 400. The multiple application integration system 400 is functionally very similar to the application integration system 200 illustrated in FIG. 3. Therefore, various reference numerals of the multiple application integration system 400 are same as the corresponding reference numerals of the application integration system 200. Specifically, the multiple application integration system 400 includes the integration engine 206 working with a number of applications, in this case, the CRM application 202, the ERP application 204 and an HR application 402.

Each of the applications 202, 204 and 402 may communicate with the message transport 216 using its respective outbound adapter. Subsequently, the integration engine 206 retrieves messages from the message transport 216 and processes them internally. The internal structure of the integration engine 206 is discussed above with respect to FIGS. 3 and 4. The integration engine 206 may be adapted to determine the source of the message retrieved from the message transport 216 and the destination of the message once it is processed. The send adapter 230 of the integration engine 206 may communicate the outgoing message to an inbound adapter of respective destination application.

While the multiple application integration system 400 illustrates the integration engine 206 working with three applications 202, 204 and 402, as one of ordinary skill in the art would appreciate, any alternate number of applications may be integrated in a similar manner.
